Zeiss are set to launch a new family of lenses at Photokina, dubbed Loxia. Rumoured to be for Sony FE full-frame mirrorless cameras (A7S, A7R, A7), the new range will be joined at the show by another Otus full-frame DSLR lens as well as new rangefinder products. Zeiss are currently running a special interactive puzzle on their blog which will eventually reveal the new Photokina 2014 products.
